First of all, I really like the ENVE compact bars and the SES Aero bars are a bit of a departure. The flat platform is very comfortable on the hands when riding the tops, and the flare actually makes riding deep in the drops more comfortable on the wrists. They are very aero and put your arms in a more streamlined position. As it turns out, I didnt need as wide of a bar as I thought. The internally routed cables make the nine look really clean. What I dont like as much when comparing the Aeros to the compact bars they are too narrow due to the flare and I still had to size up (the 46cm bars are 41cm at the hoods), they are noticeably more rigid and dont seem to dampen the bumps as much, and you have to to chop the bar ends in order to install the junction box which sacrifices some of the drop length.
